BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a partial structure of a barbellhanger, and more particularly to an innovative improved structurerevealer, which is used for a barbell hanger

2. Description of Related Art Including Information Disclosed Under 37CFR 1.97 and 37 CFR 1.98.

In the actual application of a barbell hanger, the structural typedesign of the barbell hanger is generally accepted because the barbellwith considerable weight must be firmly supported. Not only does thehanger mostly adopt the massive hollow metal tube, but also the bottomend of both left and right sides of the tube is usually fixed on thefloor through a bolt lock assembly.

In the design of the existing barbell hanger structure, the top ends ofthe two adjacent vertical tubes are usually connected through thelateral frame rods, so as to form a relatively stable frame structure.The arrangement of these lateral frame rods usually uses a reasonablelength as the size specification of one unit; however, the problem withthe conventional barbell hanger application is often when the overallstructure needs to be extended and expanded. When the span between thetwo adjacent vertical tubes needs to be enlarged, though the lateralframe rod part can be extended in its lateral length through the jointcombination, but the joint combination part will be bended in the futuredue to insufficient structural strength, which in turn causes problemsin the durability of the barbell hanger.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1, 2, 3, 4, and 5 for a preferred embodiment of theimproved structure of the barbell hanger of the present invention, theseembodiments are for illustrative purposes only and are not limited tothis structure in the patent application.

The improved structure A comprises: a vertical rectangular tube 10 witha ground end 11, a top end 12 and a tube body portion 13 between theground end 11 and the top end 12, wherein the tube body portion 13 isprovided with plural barbell positioning portion 14 arranged in an upperand lower interval (Note: this embodiment is a hole type); a horizontaltube 20 (in this case, a rectangular cross section) with a connectingend 21 and an extending end 22, the connecting end 21 is provided with afirst locking tray 23 locked and positioned with the tube body portion13 of the vertical rectangular tube 10, and the extending end 22 isprovided with a second locking tray 24; a pull-up operating frame (toextend pull-up rig section) 30 disposed transversely to the intervalbelow the horizontal tube 20, the pull-up operating frame 30 includes across bar 31 as well as a mounting end locking plate 32 and an extendedend locking plate 33 of two end relative to the cross bar 31 in thevertical plate type, wherein the mounting end locking plate 32 is lockedand positioned at one side of the vertical rectangular tube 10, thesecond locking tray 24 arranged between the extended end locking plate33 and the cross bar 20 extended end 22 is a relative relation of thelocking tray surface, which is level with each other; the two cornerreinforcing plates 40 are respectively disposed at the cross bar 31 anda corner connected with the mounting end locking plate 32 as well as thecross bar 31 and a corner connected with the extended end locking plate33; in this embodiment, the corner reinforcing plate 40 is set in atriangular plate type, which is a preferred embodiment but is notlimited thereto.

Referring to FIGS. 2, 3, 4 and 5, in this embodiment, the extended endlocking plate 33 of the pull-up operating frame 30 as well as the secondlocking tray 24 arranged in the extended end 22 of the horizontal tube20 are commonly locked to the body portion 13B of the another verticalrectangular tube 10B; in this embodiment, after the improved structure Ais combined with another vertical rectangular tube 10B, a similar

-shaped structure as shown in FIG. 5 can be formed, which is onespecific simple type of barbell hanger structure to be combined andformed in the application of the present invention.

Referring to FIGS. 6, 7 and 8, in this embodiment, the second lockingtray 24 disposed in the extended end 22 of the horizontal tube 20 aswell as the extended end locking plate 33 of the pull-up operating frame30 are more commonly connected with a connecting plate 50; theconnecting plate 50, the second locking tray 24 and the extended endlocking plate 33 are provided with plural locking holes 60 in oppositepositions for screwing through the plural screw-in positioning members70 (usually bolts and nuts); in the combined type shown in thisembodiment, the two sets of improved structure A with the same type canrealize the symmetric combined expanding state as shown in FIG. 9. Forthat this type is compared with said type shown in FIG. 5, it is assumedthat the spacing between the vertical rectangular tube 10 and anothervertical rectangular tube 10B as shown in FIG. 5 is regarded as a singlespan, and then the spacing between the two vertical rectangular tubes 10shown in FIG. 9 can be regarded as an implementation type of a doublespan, that is, the length of the horizontal tube 20 has been doubled;moreover, the purpose of the connecting plate 50 is to more firmlyposition the vertical spacing between the second locking tray 24 and theextended end locking plate 33, thereby further the pull-up operatingframe 30 and the horizontal tube 20 can reach a rigid and stable state,it can withstand strong external force and it is not easily deformed.

Referring to FIGS. 10 and 11, in this embodiment, the horizontal tube 20is provided with plural positioning holes 25 arranged at a lateralinterval for one or more adjustable lateral top frames 80 to be mountedand positioned. Each of the adjustable horizontal top frames 80 includesa transverse frame 81 and two sets of the connecting seat 82 of twoopposite ends disposed on the transverse frame 81. Each connecting seat82 is provided with plural locking holes 83 corresponding to the pluralpositioning holes 25 provided in the horizontal tube 20; the adjustablelateral top frame is disposed for the adjustable horizontal top frame80, mainly as shown in FIG. 9. When two horizontal tubes 20 with aspaced arrangement in a barbell hanger composed of the plural improvedstructure A are provided, the two horizontal tubes 20 can becross-connected and positioned by one or more adjustable lateral topframes 80, to form a more stable frame structure, and the adjustablelateral top frame 80 can also provide the hanging function of somesports aids (such as sandbags, flying rings, etc.), which is quitepractical and added value.

Referring to FIG. 12, in this embodiment, the second locking tray 24Bdisposed in the extended end 22 of the horizontal tube 20 as well as theextended end locking plate 33B of the pull-up operating frame 30 aremore commonly connected with a connecting tube 90; the connecting tube90, the second locking tray 24B and the extended end locking plate 33Bare provided with the plural locking holes 60B in opposite position, andare positioned by the plural screw-in positioning members 70B, and thesecond locking tray 24B and the extended end locking plate 33B areprovided with the zigzag tab 241 and 331 (note: the number is notlimited, the two tabs in the upper and lower intervals are shown in thefigure), so that the locking holes 60B are provided in the tab 241 and331; in this embodiment, the second locking tray 24B of the extended end22 of the horizontal tube 20 as well as the extended end locking plate33B of the pull-up operating frame 30 can also be the same type of thecommon locking connection tube 90, so it is not limited to the plateconnecting type shown in FIG. 6; furthermore, the second locking tray24B and the extended end locking plate 33B can also be provided with thezigzag surface type of the tab 241 and 331, so the position is notlimited to the flat-straight plate locking type shown in FIG. 6.

With said structural composition type and technical features, theimproved structure of the barbell hanger shown in the present inventionhas a specific application, and when the overall structure of thebarbell hanger needs to be extended or expanded or the span between twoadjacent vertical tubes needs to be expanded, the combination can beeasily and quickly achieved, and the combined part can achieve betterstructural strength and meet the requirements of sturdiness; inaddition, the pull-up operating frame 30 can provide the additionalfunctions of the horizontal bar sports, which make the whole inventionhave practical progress and better industrial utilization benefits; andthe present invention can also realize the multi-span frame extensiontype, as shown in FIG. 13, the mentioned horizontal tube 20 and thepull-up operating frame 30 can be a multi-section assembly extensiontype, and a stable combined state can be achieved through the connectionof the connecting plate 50 (or the connecting tube).
